golang - go fmt.scanf获取输入的时候，如何获取到包含空格的句子？

问题描述

问 题

我试图通过fmt.scanf输入一个句子存入变量，但是scanf函数将空格后面的单词识别成了下一次输入的内容。
请问如何避免这个问题呢？

代码如下所示：

package main

import (
    "fmt"
    "strings"
)

func main() {
    var quote string
    var name string

    fmt.Print("What is the quote? ")
    fmt.Scanf("%s", &quote)

    fmt.Print("Who said it? ")
    fmt.Scanf("%s", &name)

    fmt.Printf("%s says, \"%s\"", strings.Title(name), quote)
}

输出如下：

What is the quote? I am Groot
Who said it? Am says, "I"

已尝试过bufio包，但是我想找到只用fmt包的方法

解决方案

func main() {
    var quote string
    var name string

    fmt.Print("What is the quote? ")
    Scanf(&quote)

    fmt.Print("Who said it? ")
    Scanf(&name)

    fmt.Printf("%s says, \"%s\"", strings.Title(name), quote)
}

// Scanf
// fmt包真的就不能有空格，只能改造它的包! 呵呵。

/*

    What is the quote? 不要台固执 都是包
    Who said it? 不是你写 就是我写
    不是你写 就是我写 says, "不要台固执 都是包"

func Scanf(a *string) {
    reader := bufio.NewReader(os.Stdin)
    data, _, _ := reader.ReadLine()
    *a = string(data)
}
